Changing the default datadir.
Minor editing on the README
Just including a comment.
Working on a new class AVISO_fetch. Upgrading to version 0.4.0 Still
under work.
More progress on Class AVISO_fetch. No link to test, still unfinished.
download_LonLat is working
Bugfix, donwload_latlon and download_time are now working.

For some reason the pupynere don't likes the flush. If I split the
  download process and do a flush() before do more procedures, it
  ignores the following actions.
Adjusting the download_data. Looks like AVISO_fetch is working.

Still need to improve several things but AVISO_fetch is now working
  with the purpose to just download. The class that uses as a dictionary
  will be build to use it on the top.
